Episode complete credited cast:


Sheldon's brilliant pen pal friend, renowned quantum cosmologist Dr. Elizabeth Plimpton, is being wooed by Cal Tech. Sheldon invites her to stay with him and Leonard while in Southern California. Sheldon feels protective of her because he feels she is in the same genius class as himself. Leonard is in awe of their temporary roommate. Dr. Plimpton, however, makes it obvious to Leonard that she is interested in him more than just as a fellow scientist. Leonard has a difficult time keeping his intimate encounter with Dr. Plimptom a secret. She doesn't seem to mind as she sets her sights a little more broadly than just Leonard. Written by Huggo

Sheldon states, "Pets are banned under The Roommate Agreement, with the exception of service animals, such as seeing eye dogs and, one day, cybernetically-enhanced helper monkeys." Both Leonard and Sheldon use cats as a substitute for female companionship which violates this rule. See more »

Dr. Elizabeth Plimpton: Ah, Dr. Cooper, thank goodness. I completely forgot your address. But then I remembered that I'd written it on my hand. Lucky for me, I didn't confuse it with what I'd written on my other hand, which are the coordinates for a newly discovered neutron star. 'Cause if I tried to go there, I'd be crushed by hypergravity. Anyway, hello.

Crazy Credits

CHUCK LORRE PRODUCTIONS, #286 In public bathrooms I will sometimes use the "children's urinal" in order to feel like a giant. If no one's around, I'm likely to sing along with Aretha Franklin's version of "You Make Me Feel Like a Natural Woman, but not the Carole King version. I've never understood why anyone would bother making a porn movie that lasts longer than ten minutes. I often pretend that the person standing next to me in an elevator is an unwitting carrier of a deadly airborne disease unleashed by terrorists who hate our freedom. This, of course, forces me to hold my breath until the doors open. Forty years ago I measured my penis with a wood ruler. The irony was lost on me. Sometimes sex just seems like a lot of work. There are mornings when, for no perceivable reason, I turn into a teenage girl and repeatedly change my outfit. I floss so that my dentist will be proud of me. Even when asked, I have never been able to "talk dirty" to a woman without feeling like a complete idiot. My one attempt at manscaping ended in bloodshed. See more »

"The Plimpton Stimulation" was a funny sexually-charged ep of "The Big Bang Theory"
30 March 2011 | by (Baton Rouge, La.) – See all my reviews

In this ep of last season's "The Big Bang Theory": Sheldon has informed Leonard (per a roommate's written agreement) that a Dr. Elizabeth Plimpton (Judy Greer) is staying at their apartment. Leonard's excited since he's such a fan of her book. When she arrives, she turns out to be interested in Leonard as more than one way. When Penny finds out, she's not too gratified despite her and Leonard's recent breakup. Oh, and it turns out Dr. Plimpton has an interest in Raj and Howard as well...This was another hilarious ep of "TBBT" especially with all the sexual innuendo concerning Ms. Greer who's such a sexy and funny presence not only here but other shows and movies I've seen her in. Hope her new series "Mad Love" does well. Anyway, that's a high recommendation of "The Plimpton Stimulation".
